[Kernel-packages] [Bug 1813651] Re: hpsa: DMAR invalid read
The problem was fixed by the following commit, present in all Ubuntu
releases: 625d7d351887 ("scsi: hpsa: correct ioaccel2 chaining").
Basically it was an access to a DMA non-mapped region, and was
restricted to non-RAID mode adapters due to the I/O path being
different.
Since it was fixed, no more work or debug is necessary here.
Cheers,
Guilherme

Title:
hpsa: DMAR invalid read
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Disco:
Fix Released
Bug description:
Recently in kernel 4.20-rc1 and newer we observed the following
spontaneous issue with hpsa when intel_iommu is enabled:
[ 5173.952022] DMAR: DRHD: handling fault status reg 2
[ 5174.190649] DMAR: [DMA Read] Request device [03:00.0] fault addr eefdd000
[fault reason 06] PTE Read access is not set
There's a commit that touches DMA in hpsa: "scsi: hpsa: switch to generic DMA
API"
We've tested with this commit reverted on top of 4.20-rc1 and it reproduces
(the trigger is a kernel build). We cannot reproduce in 4.19.
Investigation is ongoing.

[Kernel-packages] [Bug 1813651] Re: hpsa: DMAR invalid read
I've narrowed down the problem for devices in HBA mode; if device is in RAID mode (despite if it's effectively using some raid level or has only 1 disk), it does not reproduce the issue. I'll attach files with outputs from HP RAID utility (accessed in BIOS) for both cases. I continue the investigation.

[Kernel-packages] [Bug 1813651] Re: hpsa: DMAR invalid read
Hi Terry, I'm planning to post an update this week. It seems the problem is related with physical block size adjustments, after the introduction of the patch: "eb53a3ea3e00 scsi: hpsa: limit transfer length to 1MB, not 512kB" Without this patch I don't see the issue anymore. But I'm investigating why this patch triggers the issue...
